<br> &nbsp;<br>
This is a C language project that demonstrates the <i>serial
peripheral interface</i> (SPI). This
project interfaces the ST7735R LCD and SDC to the microcontroller.<br>
<b>main0</b> Low level test, it will leave the SDC unformated. <br>
<b>main1</b> Simple file write and test, SDC needs FAT16 format. <br>
<b>main2</b> Longer file write and test, SDC needs FAT16 format. <br>
<b>main3</b> Will create a large binary file called Sound.bin.<br>
<b>main4</b> Will stream Sound.bin to 12-bit DAC at 11.025 kHz.
</p>
<p>First run main3 to create Sound.bin. Then, connect PB20 (TExaS scope) to PA15 (DAC output) and run main4.</p>

## Author: Ramesh Yerraballi, Jonathan Valvano
## Use this in octave to convert a wav file into raw binary
## samples with a chosen precision at 11.025kHz
## You will need to load the signal package first to use the decimate function
## You can load it like this on the octave prompt:
## pkg load signal
## Run in octave as:
## WCbin ("filename", precision);
## The inputs are (i) the name of the wav file without the extention .wav.
## (ii) the sample precision in bits (e.g., 4 to 8 bits)
## This will generate a filename.bin file that has raw binary data
## For example, say you have a sound file called boom.wav that you want to use in
## in your game.
## 1. Put the WCbin.m script and the boom.wav file in a folder (say sounds).
## 2. Open octave/matlab and cd to the sounds folder
## 3. Run script as: WCbin("boom", 8)
## For 8-bit precision
## This will produce a file named boom.bin, which contains raw samples
## You can put the file on an SDC and read the data at run time
function WCbin(filename,precision)
# load the file
[SplsOrig, fs] = audioread(strcat(filename,'.wav'));
# downsample to 11.025kHz
Spls = decimate(SplsOrig,round(fs/11025));
# trim the precision of each sample
Spls = round((Spls+ 1)* (2^precision-1)/2);
# write raw binary to file with bin extension
file = fopen(strcat(filename,'.bin'), 'w');
fwrite(file, Spls(1:length(Spls)));
fclose(file);

The 'targetConfigs' folder contains target-configuration (.ccxml) files, automatically generated based
on the device and connection settings specified in your project on the Properties > General page.
Please note that in automatic target-configuration management, changes to the project's device and/or
connection settings will either modify an existing or generate a new target-configuration file. Thus,
if you manually edit these auto-generated files, you may need to re-apply your changes. Alternatively,
you may create your own target-configuration file for this project and manage it manually. You can
always switch back to automatic target-configuration management by checking the "Manage the project's
target-configuration automatically" checkbox on the project's Properties > General page.
